We design and analyze multigrid methods for the saddle point problems resulting from Raviart-Thomas-N,d,lec mixed finite element methods for the Darcy system in porous media flow. Uniform convergence of the W-cycle algorithm in a nonstandard energy norm is established. Extensions to general second order elliptic problems are also addressed.
